ApEx 4.0: Map not showing data points correctly

In ApEx 4.0, when working with a map region (World without Greenland) (Map world/world_wo_gr.amap) you might experience that not all data points are correct.
For example: when you work with the map “World without Greenland” and you choose a query with Series Type of Bubble, Switzerland is positioned in America while Spain is in the ocean.

Oracle recognizes the bug (9950531) and will supply a fix in upcoming patch 4.0.1.
Meanwhile as a workaround the next action is suggested: setting “Series Type” to “Map”, and the countries will be correctly labeled
